This invention relates to improvements in adjustable tiling tools, andhas for its object the provision of an adjustable hand inplement for usein forming or cutting grooves upon the interior surface of buildingwalls, to imitate tiling, which may be economically manufactured, willbe reliable in operation and effective for the'purposes required.

It is often desirable to decorate the walls of halls, bath rooms orkitchens by the formation of imitation tiling, as it may be done at verysmall expense and is neat in appearance 5 in such cases, if the wallplaster is hard or brittle, the implement herein shown will readilyforni such grooves, the cutting end of the blade being disposed in therecess of the bearing-head, as will be described hereinafter if theplaster upon the wall is soft, as when newly laid, the implement isequally effective, the cutting end of the blade being disposed at thefront of the bearing-head, and used as a follower or trailer, theeffect, in either instance being that panels are formed to imitatetiling very readily, the edges and curved part of the bead or groovebeing smooth and prefectly formed.

The invention has reference to the formation of the handle,bearing-head, recesses and holding-groove of the implement, and to theparticular formation of the blades used for cutting the various groovesor beads.

With these and other objects in view, the

invention consists of the novel formation and arrangement of parts asdescribed here- 1n, pointed out by the claims, and illustrated by thedrawing, wherein,-

Figure 1 is a plan view of my newly in? shown, respectively, in Figs. 4,5 and 6. Fig. 11 is a side view of the forming-blade shown by Fig. 7.Fig. 12 is a broken away view, being a detail relating to Fig. 2, toshow mountings of the blades when used as followers, a portion of abuilding wall being added. Figs. 13 and 14 are enlarged, broken awayviews relating, respectively, to Figs. 1 l

and 2, to more clearly show arrangement of parts.

Referring now to the drawing for a more articular description, numeral 1indicates a blade-holding member, `comprising a handle 2, preferablyhaving concaved sides 3, so that the hand of an operator will be lessobtrusive to a straight-edge usually employed.

A bearing-head is indicated at 4, and is formed as a plate, rectangularin crosssection, with a first or large recess 5 opening upon one of itssides. Bearing-head 4 is also provided with a second or lesser recess 6opening upon the first recess to form a holding-flange 7 having a lengthequal to the width, transversely considered, of both recesses 5'and 6,and a length greater than half the width of head 4.

At the middle, transversely considered, of head 4, and extending fromthe front end thereof to open upon recesses 5 and 6, is formed theblade-holding groove, socket or recess 8, which is of uniform sizethroughout its length. This holding-groove opens longitudinally upon theupper surface of head 4 and has transverse walls 9 formed divergent fromthe upper surface of head 4 to the floor 10 of the groove. As thusdescribed, groove 8 is adapted to securely retain the longitudinal bodyportions 11 of any of the blades, whether the cutting ends of saidblades are disposed forwardly or rearwardly, since portions 11 havesides 16 formed convergent from their base 17 to their upper surface 18.

The upper surface 12 of the bearing-head, lower surface 13 thereof, andfloor 10 of groove 8, are parallel, and it is important that the lowersurface of head 4 be uniform or flat, so that a bearingl surface may beprovided to make proper contact with the wall ofv plaster or mortaroperated upon, to prevent the formation of rough or uneven surfaces ofthe grooves.

Handle 2 is connected to bearinghead 4 by the curved shank 14, and whenthe device is used for cutting or forming grooves in walls of plaster,head 4 is firmly pressed against the wall by manually grasping handle 2,and the instrument is drawn or pushed lengthwise, this depending uponthe blade and situation of the blade employed, as will be explained. Itis important that side edges 15 and 15, together with the intermediategroove 8, be parallel, as will be seen.

It is desirable to form a variety of grooves; cutting-blades aretherefore em loyed which differ somewhat in form, now to e described.Blade 19, shown by Fig. 5 has the concave cutting edge 20 extending tothe sides of the cutting blade. Blade 21, shown by Fig. 4 is somewhatsimilar to blade 19, exce t it has facets 22 which extend at an anglefrom the sides of the cutting blade to intersect the concaved wall 23 ofsaid cutting blade. Blade 24, best shown by Fig. 6 has a convexedcutting edge 25; this is used for cutting dry or hard Walls. When themortar upon the building wall is soft or newly laid, forming-blade 26,shown by Figs. 7 and 11, is used; it has a longitudinal stem 27 with alower, convexed surface.

In operation, the deviceis generally drawn, but may be pushedlengthwise, the lower surface 13 of the bearing-head being in contactwith the surface of building wall 28. When the body of a blade isoperatively placed in head 4, the cutting edge is somewhat lower thansurface 13, since the blades areformed with an intermediate inclinedportion 29 extending from the longitudinal body portion 11 to theterminal, ,cutting edge; and the de th of the groove formed in thebuilding wa l will, of course, be measured by the distance betweensurface 13 of the bearing-head and the cutting edge.

A straight-edge, indicated at 30 is employed, of any suitable length,and by reason of the construction shown, the device may be moved to cutseams or grooves 31, to produce an imitation of tiling upon a wall. Theseams will be uniform and there will be no uneven surfaces since theblades are adapted to cut hardened substances; and a true bearing,during operation, is secured of surface 13 of the bearing-head upon aconsiderable area of surface.

The function of recess 5 is to furnish a space suflicient forcontaining, temporarily, a part of the material cut from the wall. 1fhead 4 is drawn rearwardly, material will be cut from the wall operatedupon, and a space must be rovided for the accumulation of a part, ateast, of such material, and recess 5 must have a length adequate forthis purpose, but, as is ap arent, the length of this recess must belimited, so that the function of contact-surface 13 may be discharged,as the usefulness of the implement depends, in a large measure, upon thefacility for exerting a considerable pressure thereof, to cut the seamor groove. The function of recess 6 is to contain a part of the refusematerial which has been cut from the wall, and there should be a spaceintervening between thelblade and the side wall of this recess, asclearly shown in Figs. 1 or 13, to allow movement or passage of materialas it becomes separated from the building wall by operation of thecutting-blade.

Since groove S is located at the middle of head 4, the implement may beemployed right or left handed, that is to say, either of sides 15 or 15of the head may be in contact with the straight-edge; also on thisaccount, the tool may be used at the corner of a room, or upon abuttingwalls. When working in corners of a room, the blade may be disposed toproject at the front of head 4, as shown by Fig. 12, at which time theirnplement is moved forwardly; and when producing grooves to imitatetiling where the mortar is soft, the blade is disposed to project to thefront, the implement, however, being moved rearwardly, the blade movingas a follower or trailer. By use of the implement, whether the cuttingedge is disposed to the front or rear of head 4, and whether the wall ishard or soft, or obstructions encountered therein, the groove or seammay be formed of a uniform depth.

It will be noted that, by reason of the adjustable features shown,blades may be 'used of different patterns; these blades may be quicklyplaced in operative position in the bearing-head, or reversed from afront to a rearward position, as required.

The parts employed in the construction'of the herein described tiling-tool are few, and while there is a certain degree of exactness requiredin forming the several parts, the implement may be economicallymanufactured, and as shown and described is reliable in operation forthe rapid formation of imitation tiling upon building walls.
